Dustin Pedroia, who has played just six games for the Red Sox before returning to the injured list with left knee irritation, went 0-for-3 in his first rehab game with Double-A Portland on Thursday night.

Red Sox second baseman Dustin Pedroia will likely begin an injury rehabilitation assignment Thursday at Double-A Portland to test his balky, surgically repaired left knee that caused him to miss all but three games last season.
